Abstract

The present application provides a power device driver including a detection module coupled to the power device and configured to detect the state of the power device; a driving module coupled to the detection module and the power device respectively and configured to detect the power of the detection module. As a result, the power device is regulated; wherein the detection module includes a fast detection sub-module configured to detect a state of the power device within a preset time period after the input signal of the driving device is invalid, and controlling the driving module to softly turn off the power device when there is overcurrent. The present application also provides a corresponding power device driving method and electric equipment.
